In short I (iMac administrator) have installed turbo tax on my iMac and would like to allow the guest user account access to also use the software. Is this possible, is there a setting for this?

As far as I know it's not possible. There is not setting on an iMac to change it. I suggest going to intuit and asking them directly. There may be a setting in the software itself but I couldn't find it.

Not with Guest. You can create a new user and as long as the application allows multi user access then they can get to the application as well.
